TEXTILE-MACHINE.

" f Application filed February 12, 1916, Serial No. 78,013.

To all whom it may concern. 1

Be it known that I, JAMES LLOYD Maomns LANE, a citizen of the United States, and a resident of Atwoodville, in the county of Tolland and State of Connecticut, have invented certain new and useful Improve ments in TextileMachines, of which the following is a specification.

This invention relates to the novel arrangement and construction of textile spindles and the support thereby of bobbins or like devices, such as illustrated in my applications, S. N 0. 635,845 and S. No. 52,510.

The Word spindle as used in. the following description and claims refers to a distinctive device known by this name in'the textile "industry, usually supported at its lower end in suitable bearings and in upthough it may be more or less inclined from vertical. The object of this invention is to provide a novel spindle construction, and a novel bobbin support in connection therewith.

i bearings through the passage 6.

The drawing represents a sectionalv side view of a spindle made in accordance with my invention, and the bobbin holder for use therewith;

Referring to the drawing, a denotes what f maybe termed the base of the spindle mounted in suitable bearings I) provided with a driving means, as the belt-receiving pulley c. d is the upper bobbin receiving portion of the spindle extendlng above the bearings.

In the base of the spindle, or such part of the spindle as lies within the limits of the bearings and driving mechanism, there is a longitudinal bore, 5, and a passage 6 theref through the side of the spindle above the bearings, so that a strand or thread may be assed from one side ofthe bear ings to t e other through the spindle and carried outside of the spindle above the In the ordinary operation of a textile machine the spindle is rotated at a high rate of speed, anywhere from 8,000 R. P. M. to 11,000

- R. P. M. In accordance with this invention means are provided for mounting a nonrotating bobbin holder on the rotating spin dle, and in the embodiment of the invention illustrated in the drawing the upper end of the spindle is recessed as at 10, and mounted Specification of Letters Patent.

Patented July 17, 1917. Renewed November 17, 1916. Serial No. 131,947.

in this recess is the base 11 of the bobbin holder, the projecting end of which is overbalanced with respect to the spindle, as for instance by offsetting it as at 12.

It is found that as a result of mounting this non-rotating holder in the spindle rotating at a very high speed, the holder is subject to a certain amount of vibration, which it is desirable shall. not be communicated to the bobbin, and in order to eliminate the vibration of the bobbin, a somewhat delicate resilient device is interposed between the bobbin and the holder base 11. One means for accomplishing this result is illustrated in the drawings, and comprises a bobbin receiver 15, which is yieldingly mounted on the overbalanced end of the base 11, as by the coil spring 16. 20 denotes a bobbin or other equivalent device mounted on the receiver. The base 11 and the receiver 15 constitute what I have termed the bobbin holder and provide a substantially non-vibratory mounting of the bobbin on the spindle. As illustrated in the drawings, the bobbin is nonrotatable, it being mounted on a substantially vertical axis, but there are some arrangements in which the bobbin itself might rotate on a peculiar form of receiver, while the complete holder is not rotatable, though carried by the rotating spindle.

Two instances where the herein-described construction and arrangement of spindle and bobbin holder are of peculiar advantage are illustrated in my above-mentioned copending applications, in the first of which a strand is threaded upward through the spindle from one side of the hearings to the other and joined to a strand taken from the bobbin supported on the spindle. In the latter case, the strand from the bobbin mounted on the spindle is carried downthrough the spindle from one side of the hearings to the other.

An essential feature of this invention is the provision of means for mounting a nonrotating bobbin holder on a rotatin spindle, and the carrying of a thread t rough the bearin s inside of the spindle. These features oi construction make" possible the performance of certain operations, such as twisting and spinning strands and threads in ways which have not heretofore been utilized in the textile art, and represent great savings in power and labor, and produce a superior product of great uniformity.

This invention finds its peculiar utility and practicability in the textile industry, where the strands or threads which are be ing handled are exceedingly delicate and where for economy the work must be done at a high speed. The moving parts, such as the spindle, must be very accurately made,- very carefully balanced, and supported in carefully designed anti-friction bearings. The strands must be free from any unusual frictional drag which would impose such a tension as to cause breakage, and vibration must be overcome to as great an extent as possible, It will be observed that the spindle bearings are arranged at the lower part of the spindle, while its upper part projects above the bearings and is free and unsupported. Also, that the bobbin holder finds its sole support in the location of the base in the recess in the upper end of the spindle, providing all the essential characteristics of 'a mechanism adapted to the textile industry.

A conventional form of 'fiier, 25, is shown as secured to the upper end of the spindle, and by means of which the thread passing through the lower portion of the spindle is manipulated.

In accordance withthe provisions of the patentstatutes, I have described the principle of operation ot my invention, together with the apparatus which I now consider to represent the best embodiment thereoi; but I desire to have it understood that the apparatus shown is only illustrative, and that the'invention can be carried out by other means.
